413请求实体太大-使用Spring Boot和Rest模板

Question

使用Spring Rest模板上传一个100 MB的文件，使用多部分post请求。

HttpHeaders headers = new HttpHeaders();
    headers.setContentType(MediaType.MULTIPART_FORM_DATA);
    MultiValueMap<String, Object> map = new LinkedMultiValueMap<String, Object>();

    map.add("name", chunk.getFilename());
    map.add("filename", chunk.getFilename());
    map.add("flowChunkNumber", chunk.getNumber());
    map.add("flowChunkSize", chunkSize);
    map.add("flowIdentifier", chunk.getIdentifier());
    map.add("flowTotalSize", chunk.getTotalSize());
    map.add("flowCurrentChunkSize", chunk.getSize());
    map.add("file", chunk.getResource() );

    HttpEntity<MultiValueMap<String, Object>> entity = new HttpEntity<MultiValueMap<String, Object>>(map, headers);


    ResponseEntity<String> response = executeForResponse(
            baseUri().path("/api/v1/uploads/chunks")
                                        .build().toUri(), HttpMethod.POST, entity, String.class);

Answer 1

也许这有帮助：

SimpleClientHttpRequestFactory factory = new SimpleClientHttpRequestFactory();
factory.setBufferRequestBody(false);

RestTemplate template = new RestTemplate(factory);

当通过POST或PUT发送大量数据时，建议将此属性更改为false
